voLTAlc-ARCLAMP.

SPECIFICATION forming part of Letters PatentNo. 293,495, dated February 12, 1,884. Application filed April 20, 18553. (No model.)

.T0 LZZ whom it may concern.: v

Be it known that LOTTO A. Moses, of New York city,in the county and State of New York, have invented a new and useful Improvement in Voltaic-Arc Lamps, of which the following is a specification.

The object of my invention is to enable the light of the voltaic arc to be employedin producing signals for transmitting intelligence in maritime and military operations and for other purposes. The signals are produced by variations in and partial or entire cessations of the light ofthe arc caused by variations in the action of the feeding or regulating mechanism.

In carrying out my invention I prefer to procluding the carbons andthe electromagnetic ism, (which may be termed the signalingcircuit,) the other (which I term the incandescent circuit?) including the carbons alone. When the latter circuit is closed,the carbons remain together and are heatedto incandescence. t On breaking this circuit and closing the other, the carbons are separated, and by continuing to open and close this signaling-eircuit at intervals ilashesof light are produced.

In operating the apparatus, while the signal` ing-circuit is opened and closed, the incandescent `circuit is constantly closed, so that the come cooled, and are therefore always ready to produce the signal-flashes at once, and,`in addition, the position of the light can be constantly observed in the intervals oi' darkness between the signal-dashes by the incandescent intense and penetrating glare of the are.

Amodiication of the arrangement described consists in the use of two sets of solenoid or magnet coils, acting oppositely upon the movable carbon-carrier, and each included in a circuit, which also includes the carbons and arc. The, double action produced by opening or closing these circuits may give a quicker and more reliable action to the mechanism. The circuit of the downwardly acting solenoid should be of greater resistance than that of the other, as in moving downwardly the action oi' the magnet-or solenoid is assisted by gravity. i

In this case, also, a circuit should be provided including the arc alone without the regulating mechanism to keep the carbons constantly heated. In both forms oi' the lamp suitable dash-pots are provided, as usual, to retard and regulate the movement of the carboncarrier.

`My invention is illustrated inthe annexed drawings, in which Figure lis a diagram illustrating the rst-described form of my invention; Fig. 2, a diagram illustrating the form in which oppositely-acting solenoid or magnet coils are employed, and Fig. 3 a view of the lamp used in this latter form.

In Fig. l, c c represent, respectively, the upper and lower carbons, and b represents the upper-carbon carrier,whose movement is regulated by the magnet or solenoid c. A represents a battery or other source of electric energy. A circuit-wire, l, runs to akey, cl,which,

when depressed, makes contact with the contact-point e. A circuit-wire, 2, runs to keyyd, which makes contact at c. From contact e a "wire, 8, forming the incandescent circuit, runs, which is' connected directly with the carboncarrier b. From contact c/ the wire 4 which is the signaling-circuit, runs to the magnet or solenoid coil c. A suitable resistance, f, should be included in the incandescent circuit,to prevent a short circuit when the carbons are together.

In operating this apparatus, the key d is kept constantly depressed, whereby the incandescent circuit is' constantly maintained. When the key d is depressed, the signaling-circuit is closed, and the magnet or solenoid c raises the upper carbon and forms the arc. (ln raising the key d', the carbon-carrier drops and the are is destroyed. By varying the intervals 'of l depression, and raising of the key, flashes of light and intervals of comparative darkness of different lengths are produced, whereby signals of a prearranged code may be rendered visible at a distance. The Morse telegraphicsignals can readily beproduced in this way. A resistance, preferably an incandescing electric lamp, g, should be placed in a shunt around each `circuit-breaking point, to diminish the spark at such points.

In Figs. 2 and 3 the arrangement in which oppositely-wound coils act on the carbon-car- I rier is illustrated. It is to be understood that I Fig. 2 -is merely-a diagram intended to illustrate clearly the circuits and con nectio1is,\vhile theconstruction of the regulator is shown in Fig. 3. Oppositely-Wound coils lh and It act reversely on the carbon-carrier b."V Coilsh are in a circuit, 1 5, from the source of energy, and coils It in a circuit, l 6. Both these circuits include also the carbons a a, While an incandescent circuit is also provided including said carbons alone. The coils h act to lift the carbon-carrier, While coils 7i tend to depress it. The resistance i in the circuit including the upwardly-acting coils is greater than that in the downward circuit, as previously explained. When the circuit l 5 is closed and the circuit l 6 opened, the upper carbon is lifted, and when l 6 is closed and l 5 opened, it is quickly depressed. Circuit l 7 would be constantly closed.

The regulator which I prefer to use is substantially such as is shown in several prior applications made by me for Letters Patent, and is illustrated in Fig. 3 ofthe drawings.

C is the carbon-carrying tube containing the viscous liquid D, and inclosing the divided coreor armature E. The controlling magnet or solenoid which surrounds the tube consists in this case of two sets of coils Wound oppositely, one, h, upon the other, h', so that they act opposingly upon the tube, the divided core or armature E, and the intensifier F, which is Wound one above the'other, or in any suitable manner, so that they can both act upon the regulating mechanism.

l. A voltaic-arc lamp having tivo paths for the current, one through the regulating mechanism and the carbons, the other through the carbons alone, substantially as set forth.

2. The.colnbinatiomwith a voltaic-arc lamp, of a circuit or circuits including the regulating mechanism and the carbons, a circuit including the carbons alone, and means for opening and closing either or both of said circuits, substantially as set forth.

3. The combination, with an varc-lamp, of electro-magnetic devices acting oppositely upon the'movable carbon-carrier, and means for closing circuit to either of such devices, substantially as set forth. y

4. The combinationvith an arc-lamp, of the oppositely-acting electro-magneticV devices, a circuit energizing each ofsuch devices, and also the carbons, a circuit including the carbons alone, and a circuit-controller for each of said circuits, substantially as set forth.

This speciiication signed and witnessed this 6th day of March, 1883.
